We shouldn't use CoCreateInstance in our implementations, because some
Windows programs and Wine components use WIC without initializing COM.
This is done by calling WICCreateImagingFactory_Proxy.

In this case, I would set a value containing the bpp when setting
pixel_format. If you really need to query component info, you can use
CreateComponentInfo directly.

Of course, using CoCreateInstance and
IWICImagingFactory_CreateComponentInfo in a test is completely fine.
